Zh all whom, t may concern:

Be it known that I, ELIJAH E. WooD- ivoii'i'ii, citizen of the United States, residing' in the city and county of San Francisco and State of California, have invented new and useful lmproveiiients in Carbureters, of

which the following is a specification.

This invention relates to an apparatus for carbureting and automatically delivering fuel gas, and particularly pertains to a carburetei" for convertingl low-grade gasolene denaturedalcohol and the like into combustible gases.

lt is the object of thisinvention to provide an automatic carbureting apparatus for home use Which will furnish gas of high grade for illuminating, heating and cooking; purposes, that is .simple in construction, absolutely safe, not liable to pget out of order and which will carburet gas only as it is used, thus doing away With storage tanks.

A further object is to `provide simple means in a carburetor of this character for evaporating the liquid and mixing' it in proper proportions with air under pressure, to produce a gas without the use of heat and at low cost.

The invention consists of the parts and the construction and combination of parts as :hereinafter more fully described and claimed, having' reference to the accompanying drawings, in Whichl Figure 1 is a vertical section of the carburetor. Fig. 2 is a cross section of same. Fig'. 3 is a plan view. Fig. t is a. vertical section on the line )Q -X, Fig'. 3. Fig. 5 is a detail of the automat-ie valve operating' mechanism. Fig'. 6 is a detail of a device for adjusting` the equalizing' lever.

In the drawings A represents a cylindrical carburetertank in which is mounted a rectangular struc-ture 2, the top of which is bott-omof which is open to the interior of the tank A. This structure 2 is designed to inclose a. number of shelves or partitions 3, which are disposed in a slightly inclined position and extend in both directions entirely across the structure 2, forming a series of sepa-rate compartments or chambers l between the partitions or ioors 3. These ino; a series of perfor-ations 5 in the partitions at a point nea-r their lower ends. The partitions 3 being alternately inclined in opposite arrangement the perforations 5 in one partition are on the lopposite side of the structure 2 than those in the adjacent partitions so that iiuids passingV from one compartment d to the next 'will iioW the length of each partition or floor 3. The structure 2 and partitions 3 are preferably formed 0f Wood` or similar semiabsoi'bent material.

Air under pressure and ,qasolene' or the.y

like are admittedv to the upper compartment 4 through an inlet opening' 6 in the cover of the tank'A. This linlet opening 6 connects with a suitable source of gasolene supply through a pipe--7 which is fitted with a needle valve 8 and a. cutoftI cock 9.` 'The air supply is connected to the`pipe 7 between the needle valve Sand the inlet opening` 6 by means of a'pipe 10 which leads to a pair of ordinary Water sealed compressor tanks 11. rThese tanksvare joined together so as to ino-ve in unison and are adapt-ed to be moved upward by a piston 12 in a. cylinder 13 which is operated by hydraulic pressure from a pipe 14 connected to a Water main 15, or branch therefrom, which connects with any suitable source of Water sup ply under pressure.

A cutoff valve 16 is interposed between the pipes 14-15 to cut off or admit Water to the former, as later described. An eX- haust' pipe 17 leads from the pipe 14 and is provided with a cutoff valve 18 which is designed to be operated alternately with the valve 16. rEhe valves 16-18 are adapted to :be actuated by the rise and fall of the compressortanks 11 through the levers 19 and 2G'Which are reached by means of a weighed. rocking lever 2l pivoted on a standard 22.

rllhe lever 21 is provided with an upwardly ,extending rod 22 at one end, which .is slidably engaged by an arm 23 on the tanks 1l; in such manner that as the tanks rise or fall rp the lever-'21 Will be rocked in either direcclosed by the head of the tank A and the tion 'to open one valve 16 or 18, and close connects With the pipe 10 in the usual manner; a check valve 25 being' interposed between the tank 24 and the tanks 11, so as to 'prevent air in the former passing back to the latter.

chambers 4 are connected together by fornifollows :-Assuming the air tanks 11 moving i upward and at the upper end of their stroke.

The operation of the invention is now as In their travel upward air is drawn to the Sill lll)
